Explanation:
A CT scan of the brain is a diagnostic imaging procedure that uses special X-rays measurements to produce cross sectional images of the brain so as to provide an extra detailed information or data about brain tissue and structure concerning issues related to injuries or diseases of the brain.
During a brain CT, the X-ray beam moves in a circle around the body,and the scanner of the Ct SCAN xray starts to rotate around the body detecting the marked brain's tissues and then transmits the data to the computer. The computer will transmit the data fed into it into an image containing information that can interpreted by the radiologist.
One important procedure amongst others is to remain very still during the procedure so as to allow the right view to be captured by the scanner.
Answer:With this system, blood always flows in only one direction inside the heart. There are also valves at the bottom of the large arteries that carry blood away from the heart: the aorta and the pulmonary artery. These valves keep the blood from flowing backward into the heart once it has been pumped out.
